302 swap should I or not? Keep original or not?

[Breal]

I just bought a 84 bronco 2 clean no rust but the 2.8 needed rebuilt so I did that then the front end needed bushings. Now i paid a grand for it I've got another six hundred in it I'm thinking of just pulling the motor and doing a light 302 swap what would this cost? And what's the best donor vehicle or should I use stock ?
